SINK- TRAP.

SPECIEFECATEON forming part of Letters Patent No. 326,126, datedSeptemberlS, 1885.

Application filed June 3, 1885. (No model.) l V i To all whom it may concern:

Be it known that I, ALoIs KoEGEL, of Milwaukee, in the county ot'Milwaukee and State of Wisconsin, have invented new and useful Improvements in Sink-Traps; and I do hereby declare the following to be a full, clear, and

exact description of said invention, reference being had to the accompanying drawings, and to the letters or figures of reference marked thereon, which form a part of thisspecification.

My invention, to be hereinafter claimed, relates to sink-traps.

The object of the invention is to provide an adjustable automatic trap simple and inex-- pensive in construction and efficient inoperation. Y

The accompanying drawing illustrates a sink with the door of the case broken away, showing my trap as attached to the sink discharge-pipe, the case of the trap being also broken away on one side, showing the operative parts of the mechanism that are inside of the case.

In the drawing, A is the supporting and inclosing case of a kitchensink. A portion of the lower part of the sink is. shown at b. A discharge-pipe, c 0, leads from the sink b downward into the sewer. Beneath the sink and in the line of the discharge-pipe, and forming a part of the conduit of discharge from the sink, my trap is placed, the whole passage being water-tight from the sink to the sewer, and gas-tight at and below the valve of the trap. The trap consists of an inclosing-case made in two parts, forming the chambers d d, the upper chamber, d, being adapted to receive the liquid-discharge, and thelower chamber, d, being for the reception and movement therein of the valve and for the passage there through of the liquid-discharge from the charm ber 11 into pipe 0. The chamber d is cylindrical, having its lower end contracted by an inwardly-extending flange, e, forming a throat, the downward and outward passage from which is beveled outwardly, forming a seat, f, against which the valve closes upwardly. The lower end of the case of the upper chamber, d, is provided with an outwardly-extending flange or rigid rim, g, fitting upon a corredistinctly sponding rim, 9, on the top of the case of the lower chamber, (1, and whereby these two,

cases bymcans of bolts are attached rigidly together, forming a gas and watertight joint. The case of the lower chamber, d, is contracted downwardly, and terminates in a gasv and water tightjoint in the pipe 0. The two chambers are intended to be set vertically, as shown in the drawing, and the lower chamber, at, has the same or slightly greater diameter than the upper chamber. The free vertically: moving valve h has its periphery beveled outwardly downwardly,. and is adapted to fit tightly against the seat f on the lower side of the flange e and close the passage between the chambers d and d. The valve h is provided with a centrally-affixed rigid stem, 2', extending upwardly through'the sleeve j and through the top of the case of the chamber d, and terminating in a hook or eye, It. The sleeve j is rigid to and extends downwardly from the top of the case of chamber (1, and is a bearing or guide for the stem 6, which has a free vertical movement therethrough. The aperture through the top of the ease of chamber d is provided with apacking'nut, Z, through which the stem 6 passes, and has its vertical movement therein. The valve h and stem i are supported upon a lever, m, the short arm of which lever is inserted in the eye in the top of the stem '5. The lever m is pivoted in the arm n, extending upwardly from and rigid on the case of chamber d'. On the outer arm of this lever m is the balancingweight 0, movable and adjustable on said arm. This weight 0 can be moved in or out on the arm of the lever and so adjusted as to just balance the valve h and stem 43,- so that when any liquid whatever falls upon the valve it will open and let theliquid run through; -or the weight 0 can be so adjusted that some additional weight of liquid will be required to overcome the gravity of the weight 0 before the valve h will open and permit the liquid to pass it. It is desirable to have the weight so adjusted that it will sustain a small amount of liquid on the valve without opening, except only when the trap is used, where there is liability of the liquids freezing, in which case the weight should be adjusted to just balance the valve and stem alone and hold the valve closed when no liquid is on it, and permit it to'open at once when any liquid is discharged thereon.

It is obvious that at any time any excess of liquid on the valve h above what is required with the valve and stem to balance the weight 0 as adjusted will at once open the valve and permit the downward passage of the liquid.

The valve h moves freely downwardly into the chamber d and closes upwardly against the seat f. e

What I claim as new, and desire to secure by Letters Patent, is

The automatic gas and water tight sink trap consisting of two closed chambers, d and d, placed one above the other, the upper one being provided with an inlet-pipe, c, and the lower one being provided with an outlet-pipe, c, the flange-e extending inwardly from the wall ofthe upper chamber and forming the .partition between the two chambers, the outwardly downwardly beveled valve-seat f on the lower sidelof the flange e, the circular valve 71, having its periphery beveled inwardly upwardly, and adapted to be lifted against the seat f and close the apertures between chambers 01 and (1, said valve having a vertical movement withinthelower chamber, and beingsupported, moved, and guided by the upwardly-extending stem 73, affixed rigidly centrally to said valve and passing out through the top of the upper chamber, the sleevcj, rigid to the top of chamber b and adapted to guide the stem i in its vertical movements, and the lever m, pivoted andsupported 011 an arm on the case of the upper chamber, said lever at one end being attached to the top of stem i, and being provided on its other arm with the movable weight 0, all substantially as described, and for the purpose set forth. 7 .In testimony whereofI affix my signature in presence of two witnesses. p
